'RESILIENT CONNECTION Floyd F, and RossH. Phelps, Kcnosha,

Wis assignorsto Nash-Kelvinator vCorp'oraftion, Keno's'ha, Wis.,'a corporationbf Maryann Application January 24, 194:7,Seri'alNo. 72397-6 s'clai'ms. (01. 287 85) This invention generally relates to resilient connections and more particularly to resilient connection means foruse in connecting members of a motor vehicle'together.

It is an object of this invention to provide a resilient connection wherein mechanicatmeans and fluid rubber means are utilized to form and maintain the connection.

It is another object of this invention to provide a resilient connection which will require no lubrication or other attention after assembly thereof.

It is a further object of this invention to provide a resilient connection which is simple in design, easy to assemble and economical to manufacture.

Further objects and advantages of this invention will be apparent from a consideration of the following specification, claims and drawings in which like reference characters are used to designate similar parts, and in which:

Figure 1 is a front elevational View partially in section of a frame cross member of a motor vehicle with a front suspension unit supporting said member and showing the invention as associated with said cross member and a vehicle frame member;

Figure 2 is a sectional view of the invention as shown in Figure 1;

Figure 3 is'a'n end view of one part of the invention;

Figure 4 is a side elevational view of the part shown in Figure 3; and

Figure 5 is a sectional view of a modification of the invention shown in Figur 2.

The present invention is a resilient connection for connecting a vehicle frame cross member to a vehicle frame side rail in such a manner that shocks and vibrations will not be transmitted from the cross member to the side rail.

Illustrated in Figure 1 is a frame cross member 2 on the outer end of which is carried a suspension unit for the vehicle wheel '4. The suspension unit is generally comprised ofa lower control arm 6, an upper control arm 8, and a wheel spindle carrying member Ill which is pivotally secured between the outer ends of arms '8 and 8. A spring means (not shown) is carried by arm 6 and extends upwardly into tower 92 which is rigidly secured to the'cross member 2.

The present invention provides a resilient connection between the cross member 2 and the frame side rail M by connecting rail is to a bracket t5 rigidly secured to the top of cross member 2 and the wheel panel is likewise rigidly 2 c ed. toi hex of r flmember -c AS i rn inrigurez i rail s com se qfca 'e Q Side mbers tz whi h are p ov dw tha isnd r u e de ne b fian e flil.

Whenall the parts of the invention are assembled as described above and shown iii-Figure 2 the turning of nu't 54 o the threaded end 52 6f bolt 34 will shorten the, distance b'et eii t e zj 1'1it s4 amt-he head56 Iof bolt sta d thuspullbraglget I6 and wheel panel 18 inwardly toward each other which will compressfianges 38 of the bushi ss and tens to force the tapered stints, d2 of t plugs :40 into engagement with the-tabrd surfaces 32 of the sleeve-28 andthus expand the sleeve 2ft into more solid engagementwith the flanges 22 of the side rail I 4, The expansioncf sleeve 28 is also caused by the compression of 3 the bushings 36 and said expansion i facilitated by the provision of the longitudinal split 30 in the sleeve 28. The more nut 54 is turned on the bolt 34, the more bushings 36 will be compressed and the further the plugs 40 will be pushed into the ends of the sleeve 28.

Sleeve 28 may be threaded on its outer surface as shown at 29 in Figure 2. Such threading of sleeve 28 provides a better connection between said sleeve and flanges 22 of side rail l4 so there will be less danger of sleeve 28 moving longitudinally in relation to rail 14 after the invention is assembled.

The modification of this invention is shown in Figure in which aligned apertures 60 of rail [4 are not defined by flanges such as flanges 22 of Figure 2 but a sleeve 62 having reduced end portions 64 of slightly less diameter than the diameter of aperture 60 is pushed with portions 64 within said apertures 50. Within sleeve 62 is pushed the sleeve 28 which is of slightly less diameter than the inside diameter of sleeve 62. Sleeve 28 is expanded into frictional engagement with sleeve 62 in the same manner as described above where the sleeve 28 is expanded into engagement with the flanges 22.

In the manner described above we have provided a resilient connection for use in connecting parts of a motor vehicle so that vibrations, etc. arising in one or the other part will not be transmitted to the associated part.

While we have described our invention in some detail, this description is not to be taken as limiting the invention. All equivalents falling within the scope of the appended claims are reserved.
